双折射材料的温度修正 Birefringent Material Temperature Modification SRf.8j EkE U}2 目前,FRED尚不支持“global”温度设置,温度敏感性评估一般用脚本编程来完成,该文档演示双折射材料的折射率随温度变化的问题。附件案例文件包括两个双折射材料模,“KDP”和 “KDP Baseline”, KDP Baseline材料存储在已知温度下的折射率,KDP材料用于储存在“current”温度下的折射率值,定义为与baseline material之间的温度差。一个嵌入的脚本名为“modifyBirefringentMaterialIndex” ,包含在FRED文件中,另外也单独附加。其实现过程如下: t|y`Bl2 l\{{iAC]I 1.Retrieve the node numbers for the two materials, KDP and KDP Baseline p6e9mSs
